Jargon Free Reports

Having diagnosed leakage points, a comprehensive report outlining our findings. Everything is presented in clear, jargon-free language including advice and recommendations to resolve any issues that will lead to full compliance with the building regulations.

Air Tightness Testing Services

Greenovation measures CO2 emissions and energy leakage from domestic and commercial properties.

In The Beginning…

We work closely with decision makers and project managers on each air pressure testing project, establishing what levels of air permeability will pass or fail the test. This involves evaluating potential problems at the outset, how we intend to proceed with the testing, how much work is involved and how long it will take.

As We Progress…

The building is prepared for testing – creating an ‘envelope’ from which we can calculate air leakage and identify any air permeability problems. Results of the test are available on the same day and certificates can be issued immediately if the property has passed all assessments.

And Finally…

Having diagnosed leakage points, we will provide a comprehensive report outlining our findings. Everything is presented in clear, jargon-free language including advice and recommendations to resolve any issues that will lead to full compliance with the regulations.

Cavity Wall Inspections

The main purpose of this service is to detect dampness and to inspect existing insulation material. Cavity wall insulation will help save energy and reduce fuel bills so it’s important that, once installed, it’s not damp and is working as effectively as it should be.

Endoscopic Inspections

This is where cavity walls are examined with an endoscope to detect previous installations of insulating material and also to examine the condition of the tie-wires that hold the inner and outer layers of a cavity wall together.

Thermal Imaging

Taking thermal imaging photographs of the exterior walls of a building enables us to record the surface temperature at various points of the structure. A relatively high temperature indicates loss of heat through interior walls that are either un-insulated or poorly insulated, and that windows, doors and other parts of the building’s fabric are not functioning effectively.

What Clients Say About Us

Air Testing Testimonials

We used Greenovation for the required pressure test on our new build at Wettenhall Cheshire.

We found the company to be punctual, efficient and totally professional and would highly recommend their services.

Mark Buxton

Greenovation have completed air pressure testing across numerous new build housing sites for me for a regional residential builder across Shropshire, Staffordshire & Cheshire. Booking in is never a problem – usually with short notice and tight deadlines to achieve Part L building regulations for CML dates which Greenovation are always helpful to accommodate.

    What Is Air Pressure Testing?

    By measuring CO2 emissions and energy leakage from new or renovated domestic and commercial buildings, Greenovation will ensure compliance with UK Building Regulations.

    The purpose behind air pressure testing – sometimes known as ‘air permeability testing’ – is to strike a balance between minimising CO2 emissions (and subsequent environmental damage) whilst also ensuring that energy costs and the associated comfort factor are proportionate. In all cases, air pressure testing must make sure domestic and commercial buildings comply with relevant parts of the Building Regulations.

    Why Air Pressure Testing Matters…

    In simple terms, by making a house or commercial building as air-tight as comfortably possible, less fuel is needed to heat it. Not only does this reduce fuel bills. It also means that CO2 emissions are lower and the carbon footprint for that building is reduced.

    No building will ever be totally air-tight of course, as the occupants are continually opening and closing windows and doors. There are, however, certain aspects of a building’s construction where air can escape through gaps and cracks in various parts of the building.

    At Greenovation, we work alongside Cheshire builders and can identify the common (and less common!) causes of air leakage, or ‘air permeability’. In many cases, however, air leakage – as opposed to natural ventilation – is not always visible. Our air testing methods enable us to identify the full range of reasons why a property falls short in providing the optimum level of air-tightness.
